EV Rider N/D767A - Manual

The new N/D767a presents optimal performance in a
live sound environment. The 767a vocal microphone
utilizes EV’s new VOBÔ (vocally optimized bass)
technology to provide the performer with reduced
low-end distortion and eliminates the muddiness found
in other microphones. Combined with EV’s industry
first neodymium based magnet structure, the new
N/D767a offers the power and clarity to “cut through
the mix.”
_ VOBÔ technology provides tailored bass response for
controlled “proximity effect” and exceptional vocal
clarity
_ Supercardioid pattern for superior feedback rejection
and acoustic isolation.
_ Multistage shock mount for unmatched low-handling
noise.
_ Neodymium based magnet structure provides greater
sensitivity and signal-to-noise ratio.
_ Warm GripÔ handle for more comfortable feel.
Operation
The low frequency response of the N/D767a microphone
varies with the distance from the sound source. Known
as “proximity effect,” maximum bass response is
produced in “close-up” use with the microphone ¼ inch
from the sound source. Normal bass response is
experienced with working distances greater than 24
inches. Working close to the microphone will produce
a more robust sound. Close up positioning of the
microphone will also reduce the potential for feedback
from the sound reinforcement system. When
close-talked, the bass-boost provides an increase in
overall microphone output level. The mixer gain may
be proportionately reduced, resulting in a reduction of
the system’s sensitivity to feedback caused by sound
entering the microphone from the loudspeakers.
Microphone Use and Placement
Please note that micing techniques are a matter of
personal preference. These are merely guidelines to
assist in the placement of the microphone to gain
optimal performance.
Usage Optimal Placement
Vocals Zero to six inches from the
windscreen, and on axis with
the microphone.
Spoken
Word
Five to ten inches from the
windscreen, and on axis with
microphone.
Standard Placement & Use Guidelines
1. Always point the microphone at the desired source
of sound, and away from any unwanted sources.
2. The microphone should be located close to the
sound source to minimize interference from other
potential sound sources.
3. Use the 3-to-1 rule when using multiple
microphones. Place each microphone three times
farther from other microphones as from the
desired sound source.
4. Minimize over-handling of the microphone to
reduce unwanted mechanical noise
5. Working close to the microphone will increase the
bass tone and also provide increased
gain-before-feedback.
